Before you purchase a fogger why don't you try setting your Mistking to go on once or twice during the night for maybe 15 seconds or so to keep the humidity up. Rain at night is normal.:)
Mistking states they can be run dry without a problem but I wouldn't do it intentionally. Get yourself a 2-5 gallon covered container to draw from and only use RO or distilled water.
You will also receive a 15% discount from Josh's Frogs if you use the code REPTILIANGARDEN at checkout. But it doesn't look like he sells the 36x18x36? Give them a call.
Everything @cyberlocc said is correct. The main concern would be the sizes available. I have Carpet Chameleons which are a smaller species and glass bio vivs work well. For the veileds and panthers
l think I'd go with the clear sided Dragon Strand or build your own.
I'm raising Carpet chameleons, F. lateralis, and that's all I use. I use the Repashy at every feeding with crickets and roaches. I also feed BSFL every second or third day that do not get dusted. My female laid seventeen eggs on Memorial Day.
Now you're going to require two of everything. Find out if they're from the same parents, you shouldn't
allow them to breed together if they are. You still got a great deal. Welcome to the forum.
